AUTOMATIC RELIEF-VALVE.

To all whom it may concern:

Be it known that we, ERNST A. PLoiiGiin` and JOHN PnNRosn, citizens of the'l United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful improvements in an Automatic Relief-Valve, of which the, following is a description.

Our invention relates towtliat class of de vices or valves commonly kknown as traps or water relief valves, employed upon various parts of ka steam or other system to discharge the water o f condensation or other' fluid from the system without unnecessary waste of steam. f

Our invention has for its objectsthe con*-y struction of a simple, eilicient and reliable device of the kind described and one which may not be liable to become vinoperative owing to the accumulations of dirt or other foreign material within the valve casing.

To this end our invention consists inthe,

novel construction, arrangement and combination of parts herein shown and described and more particularly pointed out in the claims.

in the drawings wherein like reference characters indicate like or corresponding parts, Figure 1 is across sectional view of our device taken substantially on line y1-.-1 of Fig. 2, Fig. 2 is a vertical sectional view of the saine taken substantially,` on line 2-2 of Fig. 1, Fig. 3 is a view in elevation of the inlet side of our device, and Fig. 4L is avertical sectional view of afslightly modified form of device.

Referring to the drawings, as shown in Figs. 1, 2 and 3, 1 .is the' casing vprovided with an inlet or intake 2 and an voutlet 3, the discharge of fluid through the outlet being controlled by a movable valve member 4. The floor or bottom (3 ofl vthef casing proper is ypreferably inclined and formed with a pocket 7 therein at the outlet.

As is most clearly shown in Figs. 1 and '2 the bottom of the casing is preferably `eX tended above the pocket as at 8, the portion 8 being supported by the extended portions 9 leaving a plurality of substantially large openings 10 for the fluid to pass through; The movable valve-memberA which is? preferably guided by the bottom 6 and part S, is preferably made tubular and provided with a plurality .of comparatively large openings 5 so that when the valve is-inthe position shown in the full lines in Fig. 2,

the Vfluid will pass through the openings 5 and thence through the valve member and outlet 3 of the casing. Any suitable means may be employed to operate the .valve as f required. As shown the valve member l is provided with the rod 11 which is suitably,

connected to a float 15 or its equivalent through a suitable connecting'arml 12 pivlotallysupported as itt-13, the arm 12l being pivotally secured to the rod 11 as 111. rlhe icio.

Avalve member being thus connected to the iioat is controlledby the'fluid in the casing. On the part 8 of thebottoni of the casing, is preferably. arranged a shell 16 forming .what may beiternied a condensation chain- The shellis provided with an .inlet .Y

'18 preferably at the upper end thereof and is.open to theoutlet 3 whenl the valve meinber is in the position indicated iii-y thedotted lines in Fig. 2. Asshowii the valve rod'11 preferably passes through the chamber and Vthrough the opening 18, the openingbeing ofa size to give a'somewhat loose. or easy ysliding lit, or of such siZe'xas may vbe found" desirable. By having the rod 11 pass throiigli'the opening or inlet 18 the 'saine is always kept'open and prevented frontbcing clogged up. y

' L The arm 12 of, the float may be supported on' a kbracket 14 on the shell 16 vor in any N other preferred way. As shown inthe draw.V ings 4a quantity. of 'shot 19 oi' its equivalent is vpreferably placed within the float 15 or `secured thereto so that the weight ofthe float 'may Abeincieased or decreased as desired and the operation of the device be thereby lcontrolled to that, extent. An opening nor-k iiially closed `by' a lplug 26 or its equivalent is preferably arrangedy at any desired point in the casiiigto' permit access to the inte-Y In the construction shown rior of the same.

in Fig. 2 the casing ist arranged for a vertical discharge of fluid through the aux iliai-y outlet 20 or for a horizontal .discharge of fluid through the opening or auxiliary outlet '21. The auxiliary outlet not inV use isA preferably temporarily closed by ineaii's of a removable plug 23.k

Normally the valve is in the position indi@ cated'in the dotted linesin'f-Fig. 2 there beicc ing a small amountof fluid in the depression so that the valve is water sealed. A percentage of thesteam ythatenters the casing will pass or leak through the opening or inlet '18,;between the shellV and the rod 11 and be `condensed. in the condensing chamber 'i -1 f 1.1. d

thence passing through the openings 5 and through the outlet 3 of the casing. As Water or fluid enters the casing l from the inlet 2 it Will raise the float 15 so that the valve member 4 Will move substantially into the position shown in the full lines in Fig. 2, permitting the fluid to escape through the openings 5 and outlet 3 to the drain pipe 22. As the fiuid leaves the casing the float 15 returns substantially to the position indicated by the dotted lines thereby closing the valve. As before stated it is desirable to have the valve closed before all the fiuid leaves the casing so that there is a iuid seal formed around the valve at the pocket 7.

In the construction shown in Fig. 4, the casing is made in a slightly different form. Referring to this ligure 27 is the inlet 'pipe and 28 the outlet pipe. The bottom of the casing is provided With a part 34 similar to part 8 in the other device, and formed With a depression 32 to give a fluid pocket 33. The outlet 29 at the bottom of the casing is provided With a valve member 30 substantially similar to the valve member 4 in the other form. The shell 35 is arranged on the part 34 forming the condensing chamber through which passes the valve operating rod 36 which is connected by means of arms 37 or their equivalents to one or more floats 38. There may be a plurality of fioats 38 or as is obvious they may be combined in one annular float member (not shown). As shown in this figure the valve member 30 is in a position closing the outlet 29, the position of the valve members and floats When the outlet is open being indicated by the dotted lines. As shown the casing is preferably provided With a removable top 42 or its equivalent. As in the other form there is preferably a Water seal around the valve member when the same is closed. Fluid entering the casing through the inlet pipe 27 raises the float 38 and escapes through the openings 31 and outlet 29. The steam or the like Which enters the condensing chamber through the opening 39 is condensed Within the chamber and passes through the openings 40 and through the valve member into the drain pipe.

In either construction shown When the valve is closed it is sealed by a fluid seal and owing to the pocket and fluid contained therein any sediment or accumulation that may enter the casing is kept soft and thereby readily removed by the fluid when the valve is opened. Also by the construction shown We are enabled to have a larger outlet from the casing so that the Water is readily discharged and sediment easily carried through the outlet preventing any clogging up of the device. The valve operating rod passing through the condensation chamber inlet also keeps that open.

It is obvious that various immaterial modifications may be made in the form, constructionor combination of parts shown and dcscribed Without departing from the spirit of our invention, hence We do not Wish to be understood as limiting ourselves to the exact construction or combination of parts shown and described.
